The Meraki MR66 is an enterprise-class, 802.11n access point designed for rugged environments. When connected to the Meraki Cloud Controller, the MR66 enables the creation of high-speed and reliable networks that cover large outdoor and industrial areas quickly, easily, and cost-effectively. 

Package Contents

The MR66 package contains the following:

  • MR66 Cloud-Managed Access Point


  • Mount cradle


  • Wall screws, wall screw anchors


  • Mounting straps


  • Cable gland

Understanding the MR66

Your Meraki MR66 has the following features:

The Vent

The vent allows pressure and humidity equalization between the interior and the environment. This prevents internal condensation and maintains a water proof seal.

The Ground Post

The Ground Post provides an attachment point on the access point for the grounding strap (included). This post is threaded to accept a M4 x 0.7mm bolt.


The mount plate has the following features:

Antennas and Ports

The Meraki MR66 has two 802.11n radios (the MR62 has one radio). Each radio has two external antenna connectors; both connectors for a particular radio should be attached to the same type of antenna. The 5 GHz radio is used for mesh or client communication. The 2.4 GHz radio is primarily used for client communication. However, it can also communicate with Meraki 2.4 GHz access points. Meraki offers a number of different antennas for use with the MR66. Alternately, you may purchase 3rd party antennas for use with the MR66. Make sure they have N-type connectors and support the proper frequency band (2.4 GHz or 5 GHz).

Power Source Options

The MR66 access point can be powered using either a third-party 802.3af PoE switch or the Meraki 802.3af PoE injector (sold separately).

Factory Reset Button

If the button is pressed and held for at least five seconds and then released, the MR66 will reboot and be restored to its original factory settings by deleting all configuration information stored on the unit.

LED Indicators and Run Dark Mode

Your MR66 is equipped with a series of LED lights on the front of the unit to convey information about system functionality and performance.


The MR66 may be operated in “Run Dark” mode for additional security and to reduce the visibility of the access point. In this mode, the LEDs will not be illuminated. This mode may be enabled through Meraki Dashboard.

Pre-Install Preparation

You should complete the following steps before going on-site to perform an installation.

Configure Your Network in Dashboard

The following is a brief overview only of the steps required to add an MR66 to your network. For detailed instructions about creating, configuring and managing Meraki wireless networks, refer to the online documentation (

  1. Login to If this is your first time, create a new account.
  2. Find the network to which you plan to add your APs or create a new network.
  3. Add your APs to your network. You will need your Meraki order number (found on your invoice) or the serial number of each AP, which looks like Qxxx-xxxx-xxxx, and is found on the bottom of the unit. You will also need your Enterprise license key, which you should have received via email.
  4. Go to the map / floor plan view and place each AP on the map by clicking and dragging it to the location where you plan to mount it.

Check and Upgrade Firmware

To ensure your MR66 performs optimally immediately following installation, it is recommended that you facilitate a firmware upgrade prior to mounting your MR66.

  1. Attach your MR66 to power and a wired Internet connection. See the "Power the MR66" section for details.
  2. The MR66 will turn on and the LED will glow solid orange. If the unit does not require a firmware upgrade, the LED will turn green

* If the unit requires an upgrade, the Power LED will begin blinking orange until the upgrade is complete, at which point the Power LED will turn solid green. You should allow at least a few minutes for the firmware upgrade to complete, depending on the speed of your internet connection.

Check and Configure Firewall Settings

If a firewall is in place, it must allow outgoing connections on particular ports to particular IP addresses. The most current list of outbound ports and IP addresses for your particular organization can be found here

Assigning IP Addresses to MR66s

All gateway MR66s (MR66s with Ethernet connections to the LAN) must be assigned routable IP addresses. These IP addresses can be dynamically assigned via DHCP or statically assigned.

Dynamic Assignment

When using DHCP, the DHCP server should be configured to assign a static IP address for each MAC address belonging to a Meraki AP. Other features of the wireless network, such as 802.1X authentication, may rely on the property that the APs have static IP addresses.

Static Assignment

Static IPs are assigned using the local web server on each AP. The following procedure describes how to set the static IP:

  1. Using a client machine (e.g., a laptop), connect to the AP wirelessly (by associating to any SSID broadcast by the AP) or over a wired connection.
  2. If using a wired connection, connect the client machine to the MR66 either through a PoE switch or a PoE Injector. If using a PoE switch, plug an Ethernet cable into the MR66’s Ethernet jack, and the other end into a PoE switch. Then connect the client machine over Ethernet cable to the PoE switch. If using a PoE Injector, connect the MR66 to the “PoE” port of the Injector, and the client machine to the “LAN” port.
  3. Using a web browser on the client machine, access the AP’s built-in web server by browsing to Alternatively, browse to
  4. Click on the “Uplink Configuration” tab. Log in. The default login is the serial number (e.g. Qxxx-xxxx-xxxx), with no password (e.g., Q2DD-551C-ZYW3).
  5. Configure the static IP address, net mask, gateway IP address and DNS servers that this AP will use on its wired connection.
  6. If necessary, reconnect the AP to the LAN.
Static IP via DHCP Reservations

Instead of associating to each Meraki AP individually to configure static IP addresses, an administrator can assign static IP addresses on the upstream DHCP server. Through “DHCP reservations,” IP addresses are “reserved” for the MAC addresses of the Meraki APs. Please consult the documentation for the DHCP server to configure DHCP reservations.

Collect Tools

You will need the following tools to perform an installation:

Collect Additional Hardware for Installation

You will need the following tools to perform an installation:

  • Network cables with RJ45 connectors long enough for your particular mounting location
  • 802.3af PoE power source (either PoE switch or Meraki 802.3af PoE Injector)
  • Connection to the internet (if you are setting up your MR66 as a gateway to the internet)
  • Appropriately sized metal straps (if mounting to a pole larger than 3.9” in diameter)
  • Specialized mounting hardware if mounting to surface other than wood, stucco or stone

Installation Instructions

Warning: Due to the heat dissipation in the back of APs during normal operation, please do not stack powered on APs on top of each other during pre-installation to avoid heat damage.

Choose Your Mounting Location

A good mounting location is important to getting the best performance out of your MR66 access point. Keep the following in mind:

  1. The device should have unobstructed line of sight to most coverage areas. For example, if installing in an office filled with workspaces divided by mid-height cubicle walls, installing on the ceiling or high on a wall would be ideal.
  2. Power over Ethernet supports a maximum cable length of 300 ft (100 m).
  3. If being used in a mesh deployment, the MR66 should have line of sight to at least two other Meraki devices. For more detailed instructions regarding a mesh deployment, please refer to the Mesh Deployment Guide.
  4. The antennas should be as unobstructed as possible. Make sure that there is clearance around the MR66 for installation of all of your chosen antennas.

Install the MR66

For most mounting scenarios, the MR66 mount cradle provides a quick, simple, and flexible means of mounting your device. The installation should be done in two steps. First, install the mount plate to your selected location. Then, attach the MR66 to the mount plate.

Remove the Mount Plate from the Access Point

Before installing the mount plate, you must remove it from the back of the access point.

  1. Unscrew the mount plate attachment screw.
  2. Lift the mount plate release tab upwards. .
  3. While holding the mount plate release tab up, slide the mount plate off the access point in the direction shown below.

Attach the mount cradle

The MR66 mount plate can be used to install your access point in a wide range of scenarios.

Wall or Solid Ceiling Mount Using mount cradle

Using included wall anchors and screws, attach the mount plate to your mounting wall or ceiling.


It is recommended that the MR66 be mounted to a wall or solid ceiling using the mount plate for physical security reasons.

Pole Mount Using Mount Plate

Use the included mounting straps to mount the AP to a pole less than 3.9” in diameter. Thread the mounting straps through the mounting strap slots to secure the mount plate in a horizontal or vertical orientation.

Mount the MR66

Insert the posts on the back of the access point into the attachment slots on the mount plate.

Attach Antennas

Remove protective plastic covers from all four N-type RF connectors. Attach appropriate antennas (and protective boots if included).

Aim Antennas

If you are using directional antennas, aim them appropriately to ensure optimal performance for your specific network topography. Omnidirectional antennas perform best in a mesh network when oriented vertically.

Powering the MR66 with the Meraki 802.3af Power over Ethernet Injector (sold separately)

1. Plug the power cord into the PoE Injector and the other end into wall power.
2. Plug an Ethernet cable that is connected to an active Ethernet connection into the “IN“ port on the injector.
3. Route Ethernet cable from the “OUT“ port on the injector to the Eth0 port in the cable bay of the MR66.

Powering the MR66 with an 802.3af Power over Ethernet Switch

Route Ethernet cable from a port on an active 802.3af PoE switch to the Eth0 port in the bay of the MR66. The MR66 is Gigabit Ethernet-capable. To maximize device performance, a Gigabit-capable switch should be used.

Attach Power over Ethernet to the MR66
  1. Remove the dust cover from the Ethernet port of the MR66. Unscrew it with a coin or flathead screwdriver.

  2. Route the Ethernet cable from the PoE Injector “OUT” port to the MR66.
  3. Install a Cable Gland on the MR66 end of the cable.

  4. Plug the Ethernet cable into the Ethernet port of the Meraki MR66.
    1. Connect the cable to the Ethernet port on the MR66.
    2. Screw the gland body into the threaded hole of the port. Use an adjustable wrench to make sure the gland body is fully seated in the hole.
    3. Insert the split ring gasket into the gland body.
    4. Screw the cap tightly onto the gland. You may need a wrench to fully tighten the cap, but take care not to damage the cable in the process.
Attach Grounding Strap

Connect one end of grounding strap to grounding post with included screw and washer. Securely attach the other end nearby metal structure.

Verify Device Functionality and Test Network Coverage

  1. Check LEDs
    The Radio Power LED should be solid green. If it is flashing orange, the firmware is automatically upgrading and the LED should turn green when the upgrade is completed (normally in under thirty minutes). If the device is a gateway, the Ethernet LED and the four Signal Strength LEDs should be green as well. If the device is a repeater only, the Ethernet LED will not be illuminated and the number of green Signal Strength LEDs will show the signal strength to the nearest Meraki device. See section 2.6 for further details about information conveyed by the LEDs.
    Note: Your MR66 must have an active route to the Internet to check and upgrade its firmware.
  2. Verify access point connectivity
    Use any 802.11 client device to connect to the MR66 and verify proper connectivity using the client’s web browser.
  3. Check network coverage
    Confirm that you have good signal strength throughout your coverage area. You can use the signal strength meter on a laptop, smart phone, or other wireless device.
